Which are better, wooden doors and windows or plastic steel doors and windows? What is your opinion?

Plastic steel doors and windows have good air tightness: Each gap of the aluminum-plastic composite window is equipped with multiple sealing tops or rubber strips. The air tightness is level one, which can give full play to the air conditioning effect and save 50% of energy. There are many Shuogang windows installed in the decoration of old houses. "Shuogang" can make PVC doors and windows, PVC ceiling panels, and some places call them PVC profiles. Plastic steel materials have excellent performance, are easy to process and install, and have a wide range of uses. The price of broken bridge aluminum is everywhere They are all different. Sometimes they are also affected by aluminum futures and broken bridge aluminum inner fan hardware accessories.

If you are in the northern region, it is better to choose broken bridge aluminum. Broken bridge aluminum uses aluminum alloy profiles. Its material stability is better and it is more suitable for the use environment in the north with large temperature differences throughout the year. After comparing the prices, I decided to choose ordinary aluminum alloy doors and windows. The lowest price for plastic steel doors and windows starts at 300 per square meter, and the lowest price for broken bridge aluminum doors and windows starts at 500 per square meter (we are in a small county). Broken bridge aluminum alloy is a new material that has only appeared in recent years. Many of its properties can be compared with plastic steel, and it is more durable than plastic steel. The price is generally 400 to 1,200 yuan per square meter.

Comparison of wind pressure resistance. Broken bridge aluminum alloy windows are much stronger than plastic steel windows in terms of wind pressure resistance. In most cases, there is no need to add steel lining. Broken bridge aluminum alloy doors and windows are used in residential buildings with more than 40 floors. There is no problem. The disadvantages of plastic steel windows are also very obvious. Because of the special characteristics of PVC material, it will age over time, which is what we Sichuan people often call "brittle". Generally, the service life of plastic steel windows is 10 years; plastic steel time Over time, they will age and discolor (domestic plastic steel profiles generally cannot escape this fate), and broken bridge aluminum saves a lot of work in later maintenance.

Finally, there is a little reminder, which is also an issue that many people easily overlook, and that is glass. Nowadays, basically no matter what profile, it is triple-layer glass sandwiched with aluminum strips. Plastic steel windows were mostly used in old houses in the past, but now many have been replaced by aluminum alloy doors and windows.
